**Ubuntu安装git工具**

sudo apt \- get install git

git config –global user . email “test@test . com”

git config –global user . name “test”

**Ubuntu安装repo**

curl https : *//storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo*

chmod a \+ x  ~ / bin / repo

**下载Android源码**

\#此过程需要在polipo翻墙环境下进行

\#创建source目录

mkdir source

cd source

\#构建repo项目目录

repo init  \- u https : *//aosp.tuna.tsinghua.edu.cn/platform/manifest*

\#下载Android源码

repo syns

**改用科大源下载**

如果觉得慢，可以使用科大源下载源码，实际速度为你电脑网速。

**编译源码前的准备工作**

**为apt-get添加阿里云源**

deb http : *//mirrors.aliyun.com/ubuntu/ quantal main restricted universe multiverse*

deb http : *//mirrors.aliyun.com/ubuntu/ quantal-security main restricted universe multiverse*

deb http : *//mirrors.aliyun.com/ubuntu/ quantal-updates main restricted universe multiverse*

deb http : *//mirrors.aliyun.com/ubuntu/ quantal-proposed main restricted universe multiverse*

deb http : *//mirrors.aliyun.com/ubuntu/ quantal-backports main restricted universe multiverse*

deb \- src http : *//mirrors.aliyun.com/ubuntu/ quantal main restricted universe multiverse*

deb \- src http : *//mirrors.aliyun.com/ubuntu/ quantal-security main restricted universe multiverse*

deb \- src http : *//mirrors.aliyun.com/ubuntu/ quantal-updates main restricted universe multiverse*

deb \- src http : *//mirrors.aliyun.com/ubuntu/ quantal-proposed main restricted universe multiverse*

deb \- src http : *//mirrors.aliyun.com/ubuntu/ quantal-backports main restricted universe multiverse*

**安装依赖软件**

sudo apt \- get install  \- y git flex bison gperf build \- essential libncurses5 \- dev : i386

sudo apt \- get install libx11 \- dev : i386 libreadline6 \- dev : i386 libgl1 \- mesa \- devg \++ \- multilib

sudo apt \- get install tofrodos python \- markdownlibxml2 \- utilsxsltproc zlib1g \- dev : i386

sudo apt \- get install dpkg \- devlibsdl1 .2 \- devlibesd0 \- dev

sudo apt \- get install git \- coregnupg flex bison gperf build \- essential

sudo apt \- get install zip curl zlib1g \- devgcc \- multilibg \++ \- multilib

sudo apt \- get install libc6 \- dev \- i386

sudo apt \- get install lib32ncurses5 \- devx11proto \- core \- devlibx11 \- dev

sudo apt \- get install lib32z \- devccache

sudo apt \- get install libgl1 \- mesa \- devlibxml2 \- utilsxsltproc unzip m4

**添加** **OpenJDK**

安装OpenJDK

从Android 6.0开始Android源码的编译需要安装OpenJDK,不能使用Oracle JDK,而且Android 6.0只能使用OpenJDK7

sudo add \- apt \- repository ppa : openjdk \- r / ppa

sudo apt \- getupdate

sudo apt \- getinstall openjdk \- 7 \- jdk

添加配置项

export  JAVA\_HOME = / usr / lib / jvm / java \- 7 \- openjdk \- amd64

exportJRE\_HOME = $\{  JAVA\_HOME \} / jre

exportCLASSPATH = . : $\{  JAVA\_HOME \} / lib : $\{  JRE\_HOME \} / lib

exportPATH = $\{  JAVA\_HOME \} / bin : $ PATH

**编译代码**

**添加CCACHE**

为.bashrc文件末尾添加：export USE\_CCACHE = 1

echo export  USE\_CCACHE = 1  >>  ~ / . bashrc

**设置高速缓存**

为了提高编译效率，设置编译器高速缓存:

prebuilts / misc / linux \- x86 / ccache / ccache  \- M  50G

**导入Android环境变量**

导入编译Android源码所需的环境变量和其它参数:

source build / envsetup . sh

**选择编译类型**

lunch

\#选择1：aosp\_arm \- eng

**开始编译**

开始编译，执行make -j10, 10为同时编译的线程数，一般google推荐这个数字为2倍的cpu个数再加上2，比如4核，就是10。

make  \- j10

**编译成功**

**编译系统无法运行，于是使用别人提供的系统进行编译（** [http://blog.csdn.net/fuchaosz/article/details/51487585][http_blog.csdn.net_fuchaosz_article_details_51487585] **），通过上面描述的方法进行编译，编译成功。**

**运行Android** **系统**

**将配置环境到导致到上下文中**

source  build/envsetup.sh

**执行lunch**

lunch

*\#编译时选择之前编译的build target（aosp\_arm-eng）*

**配置上下文**

export  ANDROID\_BUILD\_TOP= $ANDROID\_SOURCE /

export  ANDROID\_PRODUCT\_OUT= $ANDROID\_SOURCE /out/target/product/generic/

cd  $ANDROID\_SOURCE /prebuilts/android-emulator/linux-x86\_64

**启动模拟器**

emulator

**问题汇总**

**问题1**

error :  error  opening 'out / host / darwin \- x86 / obj / SHARED\_LIBRARIES / libart\_intermediates / gc / heap.d':  No  space  left  on  device

fatal  error :  error  in  backend: IO failure  on  output stream.

ninja: build stopped: subcommand failed.

make:  \* \* \*  \[ninja\_wrapper\]  Error  1

解决方案(分区磁盘小了)

修改磁盘大小 $ sudo hdiutil resize \- size < new \- size \- you \- want > g

~ / android.dmg.sparseimage
